"Do not face towards the Qiblah nor turn your backs toward it when defecating or urinating, rather face toward the east or the west." (Using translation from Nasāʾī 21)  

أَنَّ النَّبِيَّ ﷺ قَالَ «لَا تَسْتَقْبِلُوا الْقِبْلَةَ وَلَا تَسْتَدْبِرُوهَا لِغَائِطٍ وَلَا بَوْلٍ وَلَكِنْ شَرِّقُوا أَوْ غَرِّبُوا»  

"The Messenger of Allah ﷺ said: 'When any one of you goes to defecate, let him not face toward the Qiblah, rather let him face towards the east or the west.'" (Using translation from Nasāʾī 22)  

قَالَ رَسُولُ اللهِ ﷺ «إِذَا أَتَى أَحَدُكُمُ الْغَائِطَ فَلَا يَسْتَقْبِلِ الْقِبْلَةَ وَلَكِنْ لِيُشَرِّقْ أَوْ لِيُغَرِّبْ»
